LOOM-SEAT.

Specification of Letters Patent.

Patented July 22, 1919.

Application filed February 13, 1918. Serial N 0. 216,846.

Hopedale, county of Worcester, State of.

Massachusetts, have invented an Improvement in Loom-Seats, of which thefollowing description, in connection with the accompanying drawing, is aspecification, like characters on the drawing representing like parts.

The object of this invention is to provide a seat for the operative of aloom or other similar piece of machinery so constructed and arrangedthat it will present a firm and durable seat Occupying a. minimum amountof-space and when not in use shall be movable into an inoperativeposition close to the loom or other frame and shall be yieldingly heldin such position.

The nature and objects of the invention will appear more fully from theaccompanying description and drawings and will be particularly pointedout in the claims.

In the drawings,

. Figure 1 represents a front elevation of a portion of a loom or othermachine frame with the seat embodying the invention in its closed orinoperative position;

Fig. 2 is a side elevation of the construc tion shown in Fig. 1, thedotted lines representing the parts in the position as shown in Fig. 1and the full lines representing the seat in open or operative position;

7 Fig. 3 is a view in transverse cross section of the construction shownin Fig. 2.

The invention is peculiarly adapted to a loom frame but is obviouslyuseful in connection with other machines or structures wherein it isdesired to have a movable seat of the character in question.

It is essential that the seat when in open or operative position shallpresent a firm and rigid structure capable of sustaining the weight ofthe operative and which shall occupy a minimum amount of space. It isalso desirable that the seat shall be folded to a closed or inoperativeposition snugly against the loom frame and entirely out of the way. Itis desirable also that the seat shall remain in operative positionunless positively moved by the operative to bring it to the inoperativeposition. If the seat automatically moves to inoperative position theoperative having once placed the seat in operative position may expectit to remain there and may sit down without looking and be seriouslyinjured.

In the construction illustrated, the seat is connected to the loom frame1 through the medium of a bracket 2 in turn adjustably connected to theloom frame, and this bracket is a valuable feature of the inventionbecause it enables the seat readily to be attached to any frame and inany desired pos1t1on.

In the construction illustrated the loom frame 1 is shown as made ofchannel or angle iron presenting a flange. The bracket 2 is a splitbracket made in two parts enabling it to be clamped about the flangedvertical edge of the loom frame. The part 3 of the bracket isdove-tailed or fitted into the part 4 at the abutting edges. The part 3fits snugly up against the side face of the frame and the part 4 is bentor formed to fit around behind the flange and is provided with ribs 5 toposition it against the flange and against the other part 3. The twoparts of the bracket areforced together into clamping engagement withthe frame by a bolt6. A set screw 7 passes through the rearwardlyprojecting portion of the part 4 and abuts the inside of the frame 1 andlocks the bracket at any desired point of vertical adjustment. There isthus provided a very simple and efficient means of connecting the seatto the loom frame.

' The seat proper 8 is preferably formed by striking up a metal plateinto the desired shape. This plate on the underside is formed with twodownwardly projecting lugs 9 and 10.

A strut or compression member 11 is pivotally mounted at its upper endto the lug 10 being journaled on a pin 12 projecting laterally from thelug 10 and held in place by a cotter pin 13. At its lower end thecompression member 11 is provided with a hub 14 journaled on a stud orpin 15 projecting laterally from the lower end of the bracket 2 and islikewise held in place by a cotter pin 16. This compression member isformed in a rigid manner being preferably provided with a web or rib 17so as to sustain the weight of the operative.

A- tension member 18 is pivoted at its upper end to the lug 9, a ournalpin 19 projecting from the tension member passing through the lug 9 andbeing held in place by a cotter pin 20. At its lower end the tensionmember is journaled on a pin 21 projecting from the upper end of thebracket 2 and is held in place by a cotter pin 22.

The compression member-and the tension member are of such length thatwhen the seat is swung to operative position the seat will be horizontaland will be held rigidly in position. In order to secure a desiredsteady horizontal position of the seat the strut member is provided witha laterally projecting lug 23 at its upper end against which the seatplate rests when in horizontal. position, the seat plate being flattenedpreferably opposite said lug to cooperate therewith.

With this construction when the seat is swung to inoperative position upagainst the side of the frame it will assume the position indicated indotted lines in Fig. 2 with the seat plate lying against the face of theframe and the compression and tension members passing to the side of theframe thus assuming a position entirely out of the way.

A. coiled spring 24: surrounds the hub 14; of the compression member andengages at one end the compression member and at the other end thebracket and acts to move the parts to inoperative position. The tensionof this spring is so arranged that it will not act to move the partswhen the seat is in its operative position but as soon as the seat hasbeen swung by the operative partially to a closed or inoperativeposition the force of the sprin will be suflicient to carry the parts tot e closed or inoperative position and hold them there, thus requiring apositive movement by the operative to again swing them to open orinoperative position.

Itwill thus be seen that the seat when open presents a firm, solidstructure occupying a minimum amount of space, that when closed it isentirely out of the way and is held closed by the spring, and that whenonce moved to open or operative position it will not return to itsclosed or inoperative ppsition except by the positive act of theoperative.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent is: j

1. A folding seat for looms comprising a bracket and means for attachingit to the loom frame, a seat plate, a compression member pivoted to saidseat plate and to the lower portion of said bracket, a tension memberpivoted to said seat plate and to the upper portion of said bracket,.thesaid members acting when the seat is in operative position to suetainthe weight of the operative and permitting the seat to be swung upagainst the loom frame out of the way, and a laterally projecting lug onthe upper end of one of said members contacting with the bottom of saidseat plate when in operative position and acting to position ithorizontally.

2. A folding seat for looms comprising a two-part bracket and means forclamping it to the edge of a loom frame, a seat plate, a

compression member pivoted to said seat plate and to the lower portionoffsaid bracket, and a tension member pivoted to said seat plate and totheupper portion of said bracket, and a laterally projecting lug on theupper end of one of said members contacting with the bottom of said seatplate when in operative position and acting to position it horizontally.

In testimony whereof, I have signed my name to this specification. V
